SPECFICATION forming part of Letters Patent No. 414,241, dated November 5, 1889.

Application filed November 3, 1884. Serial No. 147,139. (No model.)

To all whom it may conocan:

Be it known that I, LA VERNE W. NOYES, a citizen of the United States, residing at Chicago, in the county of Cook and State of.

Illinois, have invented certain new and useful Improvements in Grain- Harvesters, of which the following specification contains a full and complete description.

This invention consists, rst, in a novel tripping mechanism; second, in novel clutching mechanism; third, in providing the clutch with a yielding backing, which will prevent premature and imperfect engagement of its members; fourth, in a peculiar construction of binder-frame, whereby the packer-driving shaft and the lnnder-driving shaft have coincident axes within said frame, but do not bear one upon or within the other; fifth, in the combination of an obliquely-acting pack ing mechanism with a carrying-platform, whereby the grain is delivered obliquely to such obliquely situated and acting packers.

Figure l is a plan of my platform and binder, showin g the general arrangement of parts. Fig. 2 is a front elevation of the same. Fig. 3 is a front sectional elevation of the binder, showing the needle, the trip and discharger, and the packers. Fig. #l is a rear elevation of the same parts. Fig. 5 is a horizontal section through the line .r on Fig. 3. Figs. 6, 7, and S are details of the cam in the binder-driving wheel which shifts the clutch-lever. Fig. 9 is a side elevation, and Fig. l0 is a horizontal section of the clutch-shifting lever. Fig. ll is an outer side elevation of the frame. Fig.

2 is anaxial section of the clutch. Fig. 13 is a plan of one of the separable halves of the Fig. la is a transverse section of the entire clutch.

A is the binder-frame, sustained upon the main frame of the machine and arranged to be adj usted horizontally to and from the main driving-shaft by mechanism which is fully explained in my patent, No. 327,581, dated October G, 1885. The binder-frame consists of the upright support A the horizontal arm A2 under the binder-platform, and the horizontal arm A2 overhanging the binder-platform.

B is the d riving-sha-ft for the packing, bindalternation being effected in the manner and 6o by the means which will be now described.

E is a bevel-gear pinion loose on the shaft B, and kept in place by suitable retaining stops or collars e on the said shaft. E is also a bevel-gear pinion loose on the saine shaft,

and retained in place between the end of the lug A4 and a suitable retaining stop or collar e on the shaft. The gear E meshes with and drives the gear G, which is Xed to and carries the binder-shaft G. The gear E meshes 7o with and drives the gear ll, which is fixed to and carries the packer-drivin g shaft H. The axes of these shafts coincide, and their bearings are hereinafter fully described.

Between the bevel-gear E and the bevelgear E,`and feathered onto the shaft B, is the compound clutch-wheel F. Both ends of this clutch-wheel, opposed to the bevel-gears E and E', respectively, are provided with the clutchteeth f, adapted to be engaged by the clutch- 8o teeth of the said gears E and E. This clutch consists of the case F', made in halves and fastened together by bolts through the lugs f, the clutch-collars F2 and F3, inclosed' within such case, and the springs F* F4, coiled around the hubs of the clutch-collars Within the case F. The case F has a middle partition f", provided with a central'opening for the shaft B. It'has also the two interior annular grooves fA1 ft2-3 and a peripheral 9o groove f5 midway between its ends. The clutch-collars F2 and F3 have flanges f2 and f2, which engage, respectively, in the grooves f4 and fM of the case F. The width of the grooves is greater than the thickness of the fianges, and the interior cavity of the case 011 either side of the middle partition is wider than the thickness of the clutches F2 and F3 therein, so that the said clutches have a play in the case F lengthwise of the shaft B. The roo The 5 5 springs F4 F4 bear at one end against 'the flanges f2 f2 and at the other end against the middle partition f", and so tend to hold the clutch-collars F2 and F2 outward toward the bevel-gears E and E', respectively.

To the lug A5 on the arm A3 of the binderframe I secure the bracket A, to which, and closely embracing the two shoulders ab' a, so as to be guided thereby, I pivot the U -shaped or forked lever F6, which horizontally strides the arm A3 vof the binder-frame, and has its two tines or branches f6 bent inward toward each other, forming the studs f7, which engage in the shoes or bearing-pieces F7 F7, which are fitted in the peripheral groove f5 of the case. At its other end, on the other side of the arm A3, the lever F6 is provided with a stud F8, which bears against the web `g of the binder driving-gear G, and within the circle of the flange g on said wheel. The web is provided with a recess g, and oppositev thereto, on the flange g', is the cam-spur g2, the web and spur at this point forming between them the cam-groove g2, and the stud F8 is provided with a r'oll g4 to adapt it to travel through said groove with the least friction.

Instead of the stud and roll and the camgroove of the form described, the stud may be shaped as illustrated-in Fig. '7, and the groove may be bounded by the cam-surfaces of the form illustrated in Fig. 7, on the web and flange, respectively.

The operation of the structure is that as the wheel G revolves the stud F8 enters the groove g2 and the lever F6 is thereby shifted. When the stud is in contact with the web elsewhere than in the groove g3, the clutch F is engaged with the pinion E and drives the binding mechanism, including the needle actuated by the rock-shaft G50, connected by the link G to the gear-wheel G; and when the stud F8 is in the cam-.groove g2 the clutch F is in engagement with the pinion E and drives the packers. Standing at the first situation, with the binder in action, when in the revolution of the wheel G the cam-groove g2 engages the stud FB and the stud reaches the apex of the said groove, and the lever F is thereby shifted and throws the clutch F out of engagement with the gear-pinion E and into engagement with the gear-pinion E', the driving-power being thereby disconnected from the gear-wheel G, it andthe entire binding mechanism come to rest and will so remain until some means shall rotate the wheel G far enough to carry the groove beyond the stud and shift back the clutch F into engagement with the pinion E. The pressure afforded by the packers which are now being driven by engagement of the clutch F with the gearpinion E is the means for effecting the change. The gearpinion E'V drives the gearwheel Il, which carries the packer-driving shaft II', concentric with the binder-shaft G',

and journaled as hereinafter described. The4 gear H2, fixed on the rear end of the shaft lil',

drives the packer-shaft H5 by means of the intermediate gear H3 meshing with the gear H4, fixed on the packer-shaft. The grain is accumulated by the packers under the guard M, against the arm J of the bell-crank lever J, which is pivoted at j to the radial arm K2, which extends rigidly from the binder-shaft, being attached to any convenient wheel or exposed part of the shaft. As illustrated, it is forged of one piece with the dischargerarm K', and the said piece K is attached to the side of the wheel G2. The arm J2 of the bell-cranklever J extends toward the packerwheel N, revolved on the shaft H5, and has its end j bent laterally toward the face of said wheel and preferably expanded vertically, as shown, so that said end j stands in toward the face of said wheel N and close alongside the same. To the arm J2 is attached the spring J2, whose other end is attached to the gear-wheel G2, or to any convenient part which revolves with the shaft G,

and so tends to draw the arm J2 toward the shaft G', and to swing the depending arm J in towardthe packers. On the face of the packer-wheel N, I provide the stud N', j utting sideward, but not so far as to strike the arm J2 except at its laterally-bent end j. When sufficient grain has been accumulated by the packers to form a bundle, and thereby sufficient pressure is exerted upon the arm J to force it outward against the retracting effect of the spring J3, it will turn on its fulcrumj until it meets the pin N2 on the radial arm K2.

If the pressure is sufficiently great it will start the radial arln forward and initiate a revolution of the binder-shaft G'; but if it is not sufficient to start said arm K2 the arm J2, having been made to descend at its forward end, so that its expanded part j" stands over into the track of the stud n on the packer-wheel N, will be presently engaged by the stud, whereby said horizontal arm J2 is driven endwise stubbleward and thereby starts the radial arm K2 and initiatesthe rotation of the shaft G' and of the wheel G, a slight motion of which forces the cani-stud F8 out of the camgroove g3, shifts the lever F6, disengages the clutch F from the gear-pinion E', and brings it into engagement with the gear-pinion E, which, thus acquiring motion, continues the revolution of the wheel G and of the gearwheel G2, which latter wheel revolving carries around with it the radial arm K2 and the bellcrank lever J. This motion continues until the binding mechanism has made one complete revolution, and the cam-groove g3 again engages the stud F8, and, thereby shifting the lever F6 and the clutch F, brings the binding mechanism to rest. As the stud is passing into the groove and shifting the lever F6 the disengagement of the clutch F from the pinion E is progressing, and if the momentum of the wheel G and of the binding mechanism is not great the motion of thewheel and the progress of the cam-stud F8 into the camgroove, and so the shifting of the lever Fand IOO the sliding of the clutch F on the shaft B, will cease at the instant the clutch-teeth on the clutch-collar 'F2 are disengaged from the clutch-teeth on the gear-pinion E. XVhile the clutch-collar F2 is withdrawing from the Apinion E the opposite clutch-collar F3 is entering into engagement with the gear-pinion E', and both pinions revolve together during the time that the shifting of the clutch is being completed. Asimiiar overlapping of motion occurs when the clutch is shifted in the opposite direction, since the shifting motion is positive, If the clutch-teeth of the clutch-collar, by rea-- son of coming into contact point to point with the clutch-teeth of the gear-pinion, shouldA bind at the points so engaged and carry the pinion by such in ere frictional contact instead of properly meshing, a breakage of some of the connected parts would result. To prevent this possibility is the purpose of the peculiar structure of the clutch and the reason for employing therein the springs F4, for the pressure by which the points of the clutch-teeth of the clutch-collar and of the gear will be held together will be only that afforded by the spring F4, there being at the instant of such accidental engagement no other resistance than that afforded by the spring, and this force will not cause the parts to engage with sufficient firinness to drive the gear-pinion. If, therefore, such accidental engagement should occur, the spring will yield and allow the teeth of the collar to slip off the teeth of the gear, and before the next teeth on the gear are encountered the clutch will have been shifted enough farther to effect a positive and full engagement between the clutch and the gear. The shaft H, which drives the packing mechanism, is tubular and has its bearings at a and a in the arm A3 of the binder-frame. The binder-shaft G passes through the entire length of the tubular shaft H and has its bearings beyond it at both ends, the front bearing being at a? in the binder-frame at the upper end of the upright standard A and its rear bearing at aS in the frame P, an adjunct of the arm A3, which is secured to the said arm A3 beyond the bearing therein of the shaft Il. This frame P is hereinafter described. The arm A3 of the binder-frame is expanded at its front part into the shell A5 to allow room for the bevel gear-wheel H, and at the rear end it terminates in the flange A61, bearing the lugs of, which afford means of attaching the frame P, whichy is in effect an expansion of the arm, wherein space is obtained for the gear-wheel IP, and which affords bearing beyond said wheel for the rear end of the binder-shaft G. From the frame P, as integral therewith, I extend downward and grainward the hanger P in which is journaled the packer-shaf t H5. Integral with the hanger P, I make the packer-guides H6.

The packing mechanism is of familiar construction, comprising the teeth H7, pivoted to the packer-disks N and guided by the guides H6. The plane of rotation of the teeth is oblique to the binder driving-,shaft B, as the shafts H and G are oblique to the said shaft B and to the driving-wheel.

At the rear end of thebinder-shaft G outside the bearing in the frame P, is secured to said shaft the wheel O, which actuates the various parts of the knotting mechanism, which are designed to be journaled and oth erwise supported upon various extensions and lugs on said frame. The details of this structure are not illustrated, since they form no part of the present application. The needle Tis actuated in the usual manner by the rock-shaft G50, to which it is secured, said shaft being journaled in the lower arm A2 of the frame and actuated by the link G connected to the crank-arm g5 of the rock-shaft and to the wrist-pin gw of the gear-wheel G. The vertical plane of the needle is, as usual, somewhat forward 0f that of the wheel O.

In the foregoing description of the tripping and clutching mechanism, reference was made only to one trip. I find it desirable, however, in ovrder to insure the true position of the bundle, that there should be two arms against which to pack the bundle-one on each side of the binding arm or needle T. I also find it desirable to have two dischargers-one on each side of the needle-to insure the positive and direct delivery of the bundle after it is bound. The trip and discharger arms K2 and K, constituting the piece 7a, revolve completely around with the 'binder-shaft g', and I duplicate both and drive them on the rear side of the needle by mechanism which I will now describe. On the frame P, I provide the bearings p p, and in them journal the shaft G, having equal gears G5 G, fixed on its two ends outside the bearings p p. Meshing with these equal gears I provide the equal gears G2 and G3, the former fixed on the end of the shaft G (and preferably, as illustrated, integral with the wheel O) and driving the gear G5, and the latter journaled on the arm A3 of the binderframe, being made in halves g5 and g, and bolted together in place about its said bearing, as illustrated in Fig. 3. Just forward of the point at which the frame P is bolted thereto and driven by the gear G to the gear G3, I iiX the piece K4, having the two arms K5 and K, respectively, parallel and similar to the arms K and K2 of the piece K, attached to the gearwheel G2. The arm K may be provided at its outer end with a bellcrank lever J 1, similar to the bellcrank lever J, and similarly actuated and operating. It is not necessary, however, that both the bell-crank levers should have the horizontal arm extended, so as to be actuated by the stud on the packer-disk, since one of them will equally well communicate the starting motion to the bindershaft. The discharger-arms K and K5 stand in the path of revolution, ahead of the trip arms K2 K". When the necessary pressure is attained to start the trip-arms forward, they carry the shaft G and bring the binder into gear with ICO IIO

IZO

the clutch F, as above described, and their motion and that of the 'discharger is continued throughout the entire revolution, in the latter part of which the dischargers, having passed up over the arm A3, descend ahead of the trips, behind the finished and bound bundle, and discharge it to the ground, and the shaft G comes to rest with both trips and dischargers in their initial position. rlhus the trips do not come back into their position of rest until after the bundle has passed clear of the machine, and in returning to that position they follow the same direction as the bundle Which is being discharged, thus avoiding a difiiculty sometimes experienced when the trip is so constructed and located that it necessarily reverses its motion when it returns to rest, and therebyis in danger of encountering the bundle While it is being discharged.

In both tripping and discharging great advantage is derived from having tWo arms-- one on each side of the plane of motion of the binding-needle and packers and rear compresser-*since when but one arm is used to afford resistance to the packing, that arm is liable to act as a fulcrum about Which the bundle is turned into a position unfavorable for binding; and When but one arm is used to discharge the bundle the cord becomes the fulcrum and causes the bundleto be discharged endwise, and, sometimes bringing itinto a direction parallel With its own motion, passes by it lengthwise and fails to discharge it.

R is the cutter-bar platform. Its structure is described in detail in my patent, No. 327,581, dated October 6, 1885.

The conveying mechanism consists of endless chains With carrying-teeth traveling through the slots r r, in a stationary platform. In order to cause the chains to deliver the grain to the binder in an oblique position corresponding to that of the packing and binding mechanism, I construct the platform so that the carrying-teeth of the chains pass under the upper sheath of the platform and are stripped of the grain on a line extending obliquely back grainvvard from the heel of the sickle.

The details of the mode of stripping and of tripping the teeth into action are fully described in my application above mentioned.

I ind it desirable sometimes to employ, to complete thc turning of the grain into the proper oblique position, the butting-belt S, which is an endless belt driven and carried on vertical shafts at the front side of the receiving and binding platform, and having its grain-actuating ply moving from a point near the inner end of the sickle obliquely stubble- Ward toward the binder. Its operation is to push the grain endwise While also somewhat hastening the butts, and so insuring the proper oblique position of the grain when it is presented to the binding arm or needle.

should be uninterrupted; but it should act Whenever the sickle is in action. As situated and illustrated it is driven by bevel-gear on the rear end of the shaft r', Which gives motion to the platform-conveyers.

In order to obtain the'largest possible space for the accumulation of grain between the end of the platform-conveyer and the packers Without setting the binder farther toward the Wheel or increasing the space between the wheel and the sickle, I prefer to make the endless conveyers strip and deliver the grain along a line, hereinafter referred to as the clearing-line, Whose rear end shall be some distance nearer the grain end of the platform than the inner cutting-point of Vthe sickle, thereby borrowing from the platfrom rather than from the binder the space needed, and in order that the grain cut off by the inner end of the sickle may be turned back into position parallel. with the grain brought up to the clearingdine by the chains I provide the guard V, attached to the inside divider and overhangingV the platform, extending back and sloping down grainward in a direction which if continued Would intersect the platform parallel to the clearing-line, so that the grain as it falls against it Will be guided so that its heads Will move grainward and it Will reach the platform in the-desired position. Of

course it is not necessaryT that the position or slope should be exactly in accordance With the above description, and I have found that avery slight extension of the guard obliquely back grainward from the inside divider is sufn ficient to accomplish the purpose sought.
